At issue is a statement from "Witness 9," which is controversial because the witness apparently told investigators that the Zimmerman family is prejudiced and that George Zimmerman molested her when the two were both minors.

"They say a lot of bad things about black people," Witness 9 said.

In the recording, the witness claims that Zimmerman's mother proclaimed she was a racist during a conversation about the President. The witness said she could not remember an instance when George Zimmerman said or did anything that was motivated by race.

The witness claimed, however, that Zimmerman "only likes black people who act like white people."

The witness also spoke to investigators about alleged acts of molestation.

"What had lead you to come forward now?" asked an investigator.

"This is the first time I'm not afraid of him," Witness 9 said.

She said Zimmerman, who was also a minor at the time, began molesting her when she was 6 years he old. She said molestation continued into their teens.

"He would reach under the blanket and try to do things. I would try to push him off. He was bigger, stronger and older. It was in front of everybody," Witness 9 said.

O'Mara tried to block Witness 9's statements saying that they were sensational allegations that were unsubstantiated and have nothing to do with the charges Zimmerman is facing.

"The defense moved to block the public release of Witness 9's statement in a motion filed on June 18, 2012 contending 'The content of this statement is not relevant to the issues of this case, and it would not be admissible in the State's case in chief.' The motion further contends that this irrelevant statement should be withheld from public dissemination because of the substantial risk that public disclosure will lead to widespread hostile publicity which would substantially impair the Defendant's fair trial rights, and would pose a serious threat to the administration of justice," said a statement on Zimmerman's legal case website.

Zimmerman is charged with second-degree murder in the death of 17-year-old Trayvon Martin.
